Larry Frank · Answer 1

1 mole of helium gas at 0.5 atm pressure.

Since this is the lowest pressure, it will have the largest volume. In a larger volume, the gas particles have a greater space to move around in and hence, more disorder.

Kendrick Schmidt · Answer 2

D.) 1 mole of helium gas at 0.5 atm pressure.
